Kuba Suder's blog on Mac & iOS development

I’ve upgraded XCode and Interface Builder to version 3.1 recently (the update doesn’t appear in the system update, you have to download it manually, and it’s deceitfully hidden – you have to register at Apple’s developer portal to get it…). Today I’ve noticed that after the update some advanced controls were missing in IB. I had a vague memory of having a lot of additional categories of controls below the standard ones (some image views and Quicktime controls, for example), and I couldn’t find them there. This screenshot confirmed that I wasn’t imagining it. Not that I need them right now, but I might need them one day…

I was able to figure this out after a bit of googling, so I’m posting a solution here so that maybe I’ll save someone a little time. The thing is, for some reason IB forgot about some of its plugins; I think it has something to do with the “known issues” entry here in the release notes. Plugin files are located inside system frameworks. Anyway, to get them back, you need to go to IB’s Preferences → Plugins, and using the plus below the list add several framework bundles from /System/Library/Frameworks. The list more or less matches the list from the release notes, but you’ll have to experiment a bit (e.g. ImageKit and Quicktime plugins were hidden inside Quartz, and DiscRecording inside DiscRecordingUI). And that’s it, all advanced controls are available again.
